1, with different resolutions.

1.2DP line: 4K(4096X2 160)60Hz is supported.

1.4DP line: 60Hz output of (7680x4320) is supported, and it can reach 120Hz at 4K. The higher the resolution, the clearer the display effect.

2. Bandwidth.

1.2DP line: the transmission speed reaches 21.6gbit/s.

1.4DP line: The maximum bandwidth has reached 32Gbps. The higher the bandwidth, the more files are transferred.

3. price.

1.2DP line: The technical specifications are relatively old, and the price is lower than that of 1.4DP line.

1.4DP line: Because 1.4DP line can support higher resolution and better display effect than 1.2DP line, the price is much higher than 1.2DP line.

Extended data:

DP data interface is the first display communication port that relies on packet data transmission technology, which can be found in technologies such as Ethernet, USB and PCI Express. It can be used for both internal display connection and external display connection.

Unlike the previous standard, which needs to transmit the timer signal in each output differential pair, DisplayPort protocol is based on a small data message called micro-message, which can embed the timer signal in the data stream.

Its advantage is that it can achieve higher resolution with fewer pins. The application of data message also allows the expansion of DisplayPort, which means that with the passage of time, the physical communication port itself can add additional functions without major changes.
